I would like to know the differences because I am confused about it.

What is the difference between Qualitative and Quantitative Research?
In sociology at least, quantitative refers to statistical studies -- any research that explains itself through numbers. This includes polls, percentages, censes, etc. Qualitative research is much more ambiguous and usually uses methods such as interviews, participant observation. Another important point to remember is that quantitative work is designed so that it can be used to explain a large amount of phenomena -- a statistical study of a small group can theoretically be used to make predictions about the whole population. Qualitative research, however, cannot make that leap since it often tells a story of a very specific group of people that does not necessarily reflect the experiences of the whole.





Does that make sense? I bet if you wikipedia it, they would give you a much more concise answer than I can.
Reply:quantitative: the capacity, mass, the quantity or the number of items





qualitative: is the grade, the value
Reply:Qualitative relates to quality (reasoning)


Quantative relates to numbers (statistics)
